Where It Comes From
Explosives manufacturing, loading, testing, use, and disposal at military ranges and former munitions plants; breakdown products can remain in soil and groundwater [1].
How You Are Exposed
Breathing dust at work; skin contact with contaminated soil; drinking or using contaminated private well water near affected sites [1][2].
Why It Matters
Can cause skin irritation or yellowing, anemia, liver and spleen effects, and cataracts after repeated exposure. Cancer evidence in humans is inadequate; agencies have not classified TNT as a known human carcinogen [1][2].
Who Is at Risk
Explosives/defense workers and cleanup crews; people living near contaminated sites or using nearby private wells; children playing in contaminated soil [1].
How to Lower Your Exposure
Follow site advisories; avoid stained soils and restricted areas; test private wells if near ranges or former plants; use safe alternate water if contamination is found; workers should use protective gear and hygiene per safety rules [1][2].
